My original idea for it was the living room, 2x Omni 20 for use in stereo mode in conjunction with my Samsung TV. In short: Per Line in connected to the headphone jack of the TV and enjoy clean sound ... I thought ... Unfortunately, this is only one speaker Omni ... If you use the device in stereo mode, there is a nasty time offset ( approximately 1.5 seconds) between TV picture and sound from the speakers Omni. The same when I gillt via Bluetooth to the Omni's Kopple my Macbook ... thus Youtube is Watching movies on computer and hear about Omni NOT synchronously possible.
For pure music playback, I have found no fault o. Quirks.
When Harman Kardon improves the synchronicity of the device, I'd probably buy more Omni speakers.
